Dependent variables. Controlled variables. A variable is part of an experiment that can change, such as amount of light, temperature, humidity, time changes, or plant growth. In an experiment, an independent variable is a variable that either changes on its own, or you purposely change it.
One of the key factors in developing and testing scientific theories is the identification and operational definition of the variables that describe phenomena observed in the real world. Variables are measured in a research study, and they can have more than one value. There are several types of variables of interest to the researcher. Independent variables are stimuli that are manipulated in order to determine their effect on the value of dependent variables.
